Display apparatus, content displaying method, and non-transitory recording medium

ABSTRACT

A display apparatus includes a display controller that displays, on the basis of a display schedule, content included in distribution data distributed from a content distribution apparatus. The display apparatus determines whether or not content that matches the replacement rule is included in the distribution data. When displaying content included in the distribution data on the basis of the display schedule, if it is determined that content that matches the replacement rule is included in the distribution data, the display apparatus replaces the content with the replacement content and displays the replacement content.

BACKGROUND 1. Field

The present disclosure relates to a display apparatus including adisplay controller that displays, on the basis of a display schedule,content included in distribution data distributed from a contentdistribution apparatus.

2. Description of the Related Art

The following mechanism (digital signage) has been used at places suchas outdoors, stores, shopping malls, event halls, amusement facilities,and public institutions to transmit information such as advertisements,sales promotion/space production, and various guides using electronicdisplay apparatuses such as displays.

In such digital signage, generally content (a signage program) that hasbeen created and edited by a content distribution side is uniformlyreceived and displayed.

However, there are needs for displaying different items of contentdepending on, for example, the locations of display apparatuses. To thisend, for example, Japanese Unexamined Patent Application Publication No.2006-40180 discloses an information distribution system using vendingmachines in order to provide information (local information) that suitsthe locations. The system creates an integrated schedule by adjusting anationwide broadcast schedule and a local broadcast schedule, and, onthe basis of the integrated schedule and a priority level (nationwidebroadcasting is given priority), broadcasts programs selected from thenationwide broadcast and the local broadcast.

However, because content to play (signage program) is generally createdby the content distribution side and distributed to and displayed at thecontent display side, it is not easy to partially replace a program thathas already been distributed and to play the partially-replaced programaccording to the circumstances of the content display side.

When there are only a few display apparatuses at the displaydistribution side and when these display apparatuses all display thesame signage program, the content distribution side may re-create asignage program and re-distribute the program. However, in the case ofdistribution from the headquarter to branches nationwide, if there arerequests from the individual branches to partially replace the program,it takes much labor to re-create and re-distribute the signage program.

When the content distribution side is to create signage programs, ifthere are many distribution destinations and if different programs areto be displayed at the individual distribution destinations, it may benecessary to create signage programs for the individual distributiondestinations, which is not easy to do.

For example, when a branch serving as the content display side wants todisplay original content (signage program), the branch once uploads thebranch's original content to the headquarter serving as the contentdistribution side. Using the uploaded content, the content distributionside creates the branch's original signage program. Then, the contentdistribution side re-distributes the created signage program to thebranch.

SUMMARY

It is desirable to provide a display apparatus capable of easilyreplacing a program on the display apparatus side in the case ofdisplaying content distributed from a content distribution apparatus.

According to an aspect of the disclosure, there is provided a displayapparatus including a display controller that displays, on the basis ofa display schedule, content included in distribution data distributedfrom a content distribution apparatus, including: a replacement rulestorage unit that stores a replacement rule that is informationregarding replacement content replacing to-be-displayed content; and adetermination unit that determines whether or not content that matchesthe replacement rule is included in the distribution data. Whendisplaying content included in the distribution data on the basis of thedisplay schedule, if the determination unit determines that content thatmatches the replacement rule is included in the distribution data, thedisplay controller replaces the content with the replacement content anddisplays the replacement content.

According to an aspect of the disclosure, there is provided a contentdisplaying method including displaying, on the basis of a displayschedule, content included in distribution data distributed from acontent distribution apparatus, including: storing a replacement rulethat is information regarding replacement content replacingto-be-displayed content; and determining whether or not content thatmatches the replacement rule is included in the distribution data. Whendisplaying content included in the distribution data on the basis of thedisplay schedule, if it is determined in the determining that contentthat matches the replacement rule is included in the distribution data,the content is replaced with the replacement content and the replacementcontent is displayed in the displaying.

According to another aspect of the disclosure, there is provided anon-transitory recording medium storing a program for causing a computermounted on a display apparatus that displays, on the basis of a displayschedule, content included in distribution data distributed from acontent distribution apparatus, to execute a process including: storinga replacement rule that is information regarding replacement contentreplacing to-be-displayed content; and determining whether or notcontent that matches the replacement rule is included in thedistribution data. When displaying content included in the distributiondata on the basis of the display schedule, if it is determined in thedetermining that content that matches the replacement rule is includedin the distribution data, the content is replaced with the replacementcontent and the replacement content is displayed.

DESCRIPTION OF THE EMBODIMENTS

Hereinafter, embodiments of the present disclosure will be describedwith reference to the drawings. In the embodiments, the case of applyingthe present disclosure to, as an example of a display apparatus, a largedisplay apparatus, such as a display apparatus used in digital signage,capable of displaying content will be described.

1. First Embodiment 1.1 Overall Configuration

FIG. 1 is a diagram for describing the entirety of a contentdistribution system 1. In the content distribution system 1, one or moredisplay apparatuses 20 are connected to a content distribution apparatus10 (content distribution server) via a network NW.

In addition, a shared file server 30, and one or more terminalapparatuses 40 are connected to the network NW. For the convenience ofdescription, the shared file server 30 and the terminal apparatuses 40are connected to the network NW; however, the shared file server 30 andthe terminal apparatuses 40 may be connected via an external networkNW2. An example of the external network NW2 includes the Internet.

Each display apparatus 20 is a display apparatus capable of displayingcontent included in a program distributed from the content distributionapparatus 10, and includes, for example, a liquid crystal display (LCD),an organic electroluminescence (EL) display, or a light-emitting diode(LED) display.

The content distribution apparatus 10 is an apparatus for managing oneor more display apparatuses 20. For example, a content provider, aninformation provider, or an advertisement distributor registers content(program) in the content distribution apparatus 10. The registeredprogram is distributed to each display apparatus 20 on the basis of aschedule set in the content distribution apparatus 10.

Here, the term “content” in the present embodiment may include any of astill image, a moving image, audio, and text. Content includes one ormore files, and a plurality of files may be configured in folder units(directory units). A plurality of files may be collectively stored inone file (for example, may be archived in the ZIP file format or the CABfile format).

Here, a file included in content is referred to as a file of content(content file). In addition, to-be-distributed content may be contentregistered (stored) in the content distribution apparatus 10 or may bestored in an external server.

Each terminal apparatus 40 is an apparatus used by a user and is aninformation processing apparatus such as a computer, a tablet, or asmartphone. Using the terminal apparatus 40, the user can registerreplacement content, which is content for replacing distributed content.Replacement content may be stored directly in each display apparatus 20or may be stored in the shared file server 30. For example, when thereis a plurality of display apparatuses 20, if replacement content isstored in and managed by the shared file server 30, content can becollectively replaced.

The shared file server 30 is conceivable as, for example, a serverapparatus that realizes Network-attached Storage (NAS) connected to anetwork, and a file sharing function. The method for sharing files mayuse, for example, file sharing services such as Server Message Block(SMB), Common Internet File System (CIFS), Apple Filing Protocol (AFP),and Network File System (NFS), or file transfer services such as FileTransfer Protocol (FTP). In addition, file sharing may be performedusing an area in a storage device included in or attached to eachdisplay apparatus 20 and/or terminal apparatus 40.

By selecting one or more items of timetable data from amongthese selectable timetable names, schedule data can be created. Thecreated schedule data is displayed in a region R122 on the right side ofthe display screen W120. The schedule data to display may be displayedas graphics as in FIG. 6 or may be displayed as a list using text.

In this manner, the created program data, timetable data, schedule data,and content (file(s)) are stored and managed as the distribution data1422.

The display apparatus management program 1438 is a program for managingeach display apparatus 20 to which the distribution data 1422 isdistributed. To which display apparatus 20 the distribution data 1422will be distributed can be selected and determined by the administratorthrough execution of the display apparatus management program 1438.

With the distribution program 1440, the distribution data 1422 isdistributed to the selected display apparatus 20. Here, the timing fordistributing the distribution data 1422 to the selected displayapparatus 20 is certain timing, such as once a day (in the morning).Note that the number of times the distribution data 1422 is distributedmay be once or multiple times. Although the description assumes thatitems of distribution data 1422 are collectively distributed, items ofdistribution data 1422 may be distributed as occasion demands.

1.2.2 Display Apparatus

The functional configuration of each display apparatus 20 according tothe present embodiment will be described on the basis of FIG. 7. Thefunctional configuration of the display apparatus 20 includes, asillustrated in FIG. 7, a controller 2000, a display unit 2100, acommunication unit 2300, and a storage unit 2400.

The controller 2000 is a function unit for controlling the entiredisplay apparatus 20. The controller 2000 realizes various functions byreading and executing various programs stored in the storage unit 2400,and includes, for example, a CPU.

The display unit 2100 is a function unit (device) capable of displayinginformation such as various images and text and is a function unit fordisplaying content (such as a still image, a moving image, and text).The display unit 2100 includes, for example, an LCD or an organic ELdisplay. Alternatively, content may be displayed (projected) by aprojector or the like, or the display unit 2100 may be an externaldisplay device connected by High-Definition Multimedia Interface (HDMI)(registered trademark), Digital Visual Interface (DVI), or the like.

The communication unit 2300 is a function unit for connecting to anetwork.

In addition, a storage area, namely, a shared file storage section 3410for storing replacement content 3412 is secured in the storage unit3400. Replacement content may be stored in a file sharable place,instead of in the display apparatus 20. Although a place wherereplacement content can be stored is described as the shared file server30 in the present embodiment, replacement content may be stored in, forexample, the terminal apparatus 40, or an area may be provided in thestorage unit 2400 of another display apparatus 20.

As the file sharing mechanism, the file sharing mechanism of the relatedart, which has been described above, may be used, and a detaileddescription thereof is omitted.

1.3 Flow of Process

Next, the flow of a process according to the present embodiment will bedescribed with reference to the drawings.

1.3.1 Flow of Replacement Rule

At first, the outline of the overall mechanism for replacement using areplacement rule will be described. The content distribution apparatus10 distributes generated distribution data to the display apparatus 20.In the display apparatus 20, the distribution data distributed from thecontent distribution apparatus 10 is stored as the distribution data2412 in the distribution data storage section 2410. The distributiondata 2412 is played and displayed by the content playing program 2442.

Here, when replacement content is stored on the display apparatus 20side, content to be displayed on the basis of the original distributiondata is replaced by the replacement content, and the replacement contentis displayed. To replace content or a program, a replacement rule isset.

The set replacement rule is stored as replacement rule data in a place(such as a folder) different from that of the distribution data.

Here, the folder configuration will be described with reference to FIG.9. Content to be displayed on the display apparatus 20 is stored in adata folder F102. Here, distribution data received from the contentdistribution apparatus 10 is stored in a schedule data folder F104(Inside folder). The content playing program 2442, which is a displayingprogram, obtains distribution data stored in the folder F104.

Here, when replacement rule data is stored in a replacement rulemanagement folder F106 (Replace folder) stored in a control file(setting file), the replacement rule data is obtained. Here, thereplacement rule data is stored in a replacement rule folder F108 (AShopfolder). Here, because a plurality of items of replacement rule data canbe stored in the folder F106, each item is stored in a child folder;however, these items may be stored in the folder F106.

In accordance with the replacement rule data, a file of replacementcontent is obtained from a replacement content folder F110 (Contentfolder). When generating replacement rule data, the replacement rulesetting program 2444 copies content (file) from a reference destinationfolder and stores the content (file) in the replacement content folderF110. The reference destination folder may be in the display apparatus20 or may be in the shared file storage section 3410.

In accordance with a rule described in the replacement rule data,specified content/program is replaced with replacement content (file)and the replacement file is displayed. At this time, a playlist isgenerated from the replacement content (file), and the replacementcontent (file) is displayed.

1.3.2 Replacement Rule Setting Process

A process of actually setting a replacement rule will be described withreference to FIG. 10. At first, when an operation for setting an updateinterval is performed, an update interval setting process of setting anupdate interval is executed (from YES in step S102 to step S104). Here,the update interval is the timing to check the reference destinationfolder, and, if a file in the reference destination folder has beenupdated, to-be-displayed replacement content is also updated. Althoughthis processing is described as part of the process in the presentembodiment, this processing may be executed in another process.

Next, when an operation for adding a replacement rule is performed (YESin step S106), a replacement-source rule (step S108) and areplacement-destination rule are set (step S110). By setting thereplacement-source rule and the replacement-destination rule inassociation with each other, the rules are set as a replacement rule.This processing is repeatedly executed until the process is completed(from NO in step S112 to step S102).

When all replacement rules are added, the replacement rule data isupdated (step S114), and the process ends.

Although the process of adding a replacement rule has been described inthe above-described flow of the process, needless to say, a process ofediting an already- set replacement rule, and a process of deleting areplacement rule are similarly executable.

An exemplary screen in the case of executing the process will bedescribed with reference to FIG. 11. FIG. 11 illustrates an example of adisplay screen W130 in the case of adding, editing, or deleting areplacement rule. Here, when an adding process is selected by anaddition button R130, the display screen W130 is switched to a displayscreen W140 in FIG. 12.

On the display screen W140, as an example, a reference folder at thereplacement destination is selectable. Various items of data, such asfiles and folders, are selectable as the replacement destination.

This time, it is assumed that a certain program has been selected as thereplacement source. As a replacement-source rule, for example, a programor to-be-distributed content (content file) is selectable.

Replacement Rule

Here, representative ones among those that are set as replacement ruleswill be described.

(1) File Replacement

In distributed distribution data, one file is replaced with anotherfile. For example, the replacement rule is set as follows:

Picture1.jpg→AnotherPicture1.jpg

As a representative example, for example, a company-wide logo can beswitched to a store-original logo.

(2) File Replacement (Multiple)

In distributed distribution data, one file is replaced with a pluralityof consecutive files. For example, the replacement rule is set asfollows:

Picture1.jpg→AnotherPicture1.jpg, AnotherPicture2.jpg

(3) File Skipping

In distributed data, one file is skipped, and the data is played. Inthis case, initial content for replacement may be separately specified,or the display duration of content before and after the content ofinterest may be adjusted:

Picture1.jpg→

(4) Program Replacement

A program is entirely replaced with a file or files in a specifiedfolder. In this case, the specified folder may be a local folder or ashared folder:

Program1→[C:

LocalFolder

Folder1]

Program1→[

NetworkFolder

Folder1]

(5) Specification of Multiple Conditions

Some replacement rules among the above-described replacement rules maybe combined. For example, a replacement rule such as one that replaces acontent file only in a certain program may be used.

Program1 and Picture1.jpg→AnotherPicture1.jpg

In the case of the above-described replacement rule, the content file“Picture1.jpg” included in the program “Program1” is replaced.

(Program1 or Program2) and Picture1.jpg→AnotherPicture1.jpg

In the case of the above-described replacement rule, the content file“Picture1.jpg” included in the program “Program1” or “Program2” isreplaced.

(6) Conditional Replacement

A replacement rule such as one that applies the above-mentionedconditional replacement rule(s) only in a certain time slot may be used.For example, a replacement rule that normally uses content ofdistribution data but replaces a program or a file only for a certaintime may be used.

Timetable1 & 15:00-15:15→[

NetworkFolder

Folder1]

In the case of the above-described replacement rule, the program isreplaced with content in the shared folder only for 15:00 to 15:15 inTimeTable1.

1.3.3 Content Display

Next, a content displaying process will be described with reference toFIG. 13. The process in FIG. 13 is a process realized by executing thereplacement rule executing program 2446 and the content playing program2442.

At first, schedule data is read (step S202). Here, when there is newlyreceived schedule data, the schedule data is re-read (from YES in stepS204 to step S206). Next, a playlist is expanded from the schedule data(step S208). Specifically, the schedule data, timetable data, andprogram data are expanded. When there is no replacement rule data (NO instep S210), content is displayed in accordance with the playlist (stepS220).

Here, when there is replacement rule data (YES in step S210), thereplacement rule data is read (step S212). Here, whether or not there isreplacement rule data may be determined by determining whether or notthere is a control file or whether or not the replacement rule data 2422is stored.

When the replacement target and condition match the playlist, that is,when there is one in the replacement source data that matches theplaylist (YES in step S214), the corresponding portion is replaced withthe replacement destination data (replacement content), and the playlistis updated (step S216).

Here, a to-be-replaced target is content or a program corresponding toeach element stored in the replacement rule data. Specifically, when thetarget of the replacement rule is “content”, it is determined whetherthere is content that matches the element “content”, and, if there issuch content, the content is replaced with the replacement content.

Alternatively, if the target of the replacement rule is not “content”but is “program”, comparison is done using a program data name. If thereis a program data name that matches the target of the replacement rule,the details of the program are replaced with the replacement content asit is.

When the processing of all items of replacement rule data is completed(YES in step S218), content (content file(s)) is displayed in accordancewith the playlist (step S220). If the processing of all items ofreplacement rule data is not completed (NO in step S218), the next itemof replacement rule data is read (step S222), and the processing isrepeatedly executed from step 5214 onward.

1.4 Exemplary Operation

Next, the flow of an exemplary operation according to the presentembodiment will be described with reference to FIGS. 14A and 14B. Atfirst, the case where there is the following replacement rule 1 as areplacement rule will be described:

Replacement Rule 1

CompanyLogo.jpg→StoreInformation.jpg

Distribution data distributed from the content distribution apparatus 10includes, as content, “CompanyLogo.jpg”, “Ad1.mp4”, “Ad2.mp4”, and“Ad3.mp4” (FIG. 14A).

Here, the content in FIG. 14A is replaced according to theabove-mentioned replacement rule. That is, content C102 is replaced withcontent C112, and the playlist becomes as follows:

“StoreInformation.jpg”→“Ad1.mp4”→“Ad2.mp4”→“Ad3.mp4”,

and the content is displayed.

In addition, the case where there is the following replacement rule 2will be described:

Replacement Rule 2

Program1

[

NetworkFolder

Folder1]

Distribution data distributed from the content distribution apparatus 10includes, as a program C122, “Product1.jpg”, “Product2.jpg”, and“Product3.jpg”.

Here, as the replacement rule, the place of a shared folder (such as “

NetworkFolder

Folder1” indicating the place of the shared file server 30) is set inthe replacement rule. Thus, the program C122 is replaced such thatcontent included in the program is replaced by content included in theshared folder.

That is, “RecommendedProduct1.jpg”, “RecommendedProduct2.jpg”,“RecommendedProduct3.jpg”, and “RecommendedProduct4.jpg” are included ascontent C132. When replaced with these items of content, the programitself is replaced.

If there is no replacement content even when there is a replacementrule, content included in the original distribution data may bedisplayed, or content in the case where there is no replacement contentmay be displayed.

In this manner, according to the present embodiment, with the use of areplacement rule, a program/content distributed from the contentdistribution apparatus 10 can be easily replaced with desired content onthe display apparatus 20 side.

Because content is stored in a folder different from that ofdistribution data, the distribution data can be prevented from beingdestructed by an operation error or the like.

2. Second Embodiment

Next, a second embodiment will be described. The second embodiment is anembodiment in the case where, when displaying content (program), contentis allocated to a display frame and is displayed. Note that thefunctional configuration is identical to that in the first embodiment,and differences from the first embodiment will be mainly described.

FIG. 15A is a diagram illustrating an example of a screen for settingdisplay frames. Display frames are regions into which a region fordisplay is divided, and corresponding content is played in each displayframe. For example, in FIG. 15A, display frames set in a region R200 aredisplayed, and it is displayed that there are regions that are namelydisplay frame 1, display frame 2, display frame 3, and display frame 4.

In addition, the details of the size of each display frame are set in aregion R202. Here, only one display frame may be used, or the regionR200 may be divided into two or three display frames and displayed.

Information (attribute) of the display frame(s) may be included in theprogram data. For example, FIG. 15B illustrates an example of theprogram data. The program data includes the coordinates of each displayframe, and content to be displayed in that display frame.

In the present embodiment, the display frame(s) can be included in areplacement attribute.

Frame1→AnotherPicture1.jpg, AnotherPicture2.jpg

For example, in the case of the above-mentioned replacement rule,content in the display frame 1 (Frame1) is replaced with two image files(AnotherPicture1.jpg, AnotherPicture2.jpg) on the basis of thereplacement rule.

Frame1→[C:

LocalFolder

Folder1]

In addition, in the case of the above-mentioned replacement rule,content in the display frame 1 (Frame1) is replaced with content storedin the local folder [C:

LocalFolder

Folder1] on the basis of the replacement rule, and a playlist isgenerated. The content after the replacement based on the replacementrule is displayed/played. As has been described above, needless to say,items of replacement rule data may be combined.

Program1 and Frame1→[

NetworkFolder

Folder1]

In the case of the above-mentioned replacement rule, the rule replacesthe details of Program 1 displayed in the display frame 1 with contentin the shared folder.

FIG. 16 illustrates an example of a display screen W210 for setting areplacement rule. As indicated in the display screen W210, in the caseof setting a replacement rule, a display frame can be set, as indicatedin a region R210. Accordingly, a display frame where content to which areplacement rule is applied is specified, and content such as a programplayed in the display frame is replaced.

3. Third Embodiment

Next, a third embodiment will be described. The third embodiment is anembodiment in the case where a distributed content file is replaced witha replacement content file and the replacement content file isplayed/displayed by placing the replacement content file in areplacement folder, instead of generating a replacement rule. Note thatthe functional configuration is identical to that in the firstembodiment, and differences from the first embodiment will be mainlydescribed. Because a replacement rule is unnecessary (or set in advancein a program) in the present embodiment, the replacement rule data 2422need not be stored. In addition, the replacement rule setting program2444 and the replacement rule executing program 2446 need not be stored.As has been described above, the functional configuration of eachapparatus is not an essential element, and, needless to say, may not beprovided (not stored) as the need arises depending on each embodiment.

An example of a folder configuration according to the present embodimentwill be described with reference to FIG. 17. In FIG. 17, a content filestored in a folder F302 of the display apparatus 20 is to be displayed.

Here, distribution data distributed from the content distributionapparatus 10 is stored in a folder F304 (Inside folder). The contentplaying program 2442 displays the content file stored in the folderF304.

Here, when a content file is stored in a replacement folder F306(Replace folder), the content file stored in the replacement folder F306is displayed as the need arises.

Specifically, for example, when the folder F306 contains a frame name(Folder F308/Frame1 folder) and a program name (Folder F310/Program1folder), the program name displayed in this frame is replaced with thedetails in the folder F310 and the details are displayed.

In addition, the file name of a replaceable content file may bedetermined in advance. For example, it is assumed that the file name“CM.JPG” is included as the file name of a replaceable content file. Inthis case, when the user stores another file with the name “CM.JPG” inthe folder F306, the distribution data can be easily displayed.

4. Fourth Embodiment

Next, a fourth embodiment will be described. In the fourth embodiment,the case of setting “rewriting prohibited” (flag) in distribution datawhen each user is not allowed to replace content without permission willbe described. Note that the functional configuration is identical tothat in the first embodiment, and differences from the first embodimentwill be mainly described.

The content distribution apparatus 10 stores a replacement-prohibitedflag in to-be-distributed content. There are several ways to store theflag. For example, a replacement-prohibited flag may be provided in thedistribution data 1422, or a replacement-prohibited content list may beseparately stored.

Also on the display apparatus 20 side, in the case ofreplacement-prohibited content, for example, the replacement rulesetting program 2444 may be configured not to be able to set areplacement rule, or the content playing program 2442 may be configuredto ignore a replacement rule even if there is a replacement rule whenplaying/displaying content.

Accordingly, for example, important information or an advertisement thatis already scheduled to be distributed is not replaceable on the displayapparatus 20 side, and content intended by the administrator can bedisplayed.

5. Fifth Embodiment

Next, a fifth embodiment will be described. In the fifth embodiment, anembodiment in which, for example, the display duration or the like ofcontent can be set by the file name of replacement content will bedescribed. Note that the functional configuration is identical to thatin the first embodiment, and differences from the first embodiment willbe mainly described.

Specifically, in step S216 of FIG. 13, a process illustrated in FIG. 18is executed when generating a playlist.

At first, the end of the file name of replacement content is extracted(step S402). The display duration of the replacement content can bedescribed at the end of the file name. Therefore, when a timerepresenting character string is not included at the end of the filename of the replacement content (NO in step S404), the playlistinformation is replaced with the replacement content as usual, and thedisplay duration is set to a default display duration.

Alternatively, when a time representing character string is included atthe end of the file name of the replacement content (YES in step S404),the playlist information is replaced with the replacement content, andthe display duration is set to a time extracted from the timerepresenting character string (step S408).

For example, in the case of “Picture_15s.jpg”, the still image“Picture.jpg” is played for 15 seconds. In the case of“slide_1m30s.ppt”, the slide file “slide.ppt” is played/displayed for 1minute and 30 seconds.

In this case, the default display duration may be set as 10 seconds, forexample. In the case of a moving image file, the original displayduration may be set as the display duration.

6. Sixth Embodiment

Next, a sixth embodiment will be described. In the sixth embodiment, anembodiment in which a replacement rule is forced to be reset, or contentis forced to be rewritten with new distribution data on the contentdistribution apparatus 10 side will be described. Note that thefunctional configuration is identical to that in the first embodiment,and differences from the first embodiment will be mainly described.

There are various ways to restore content that has been replaced at theinitiative of the content distribution apparatus 10 side to distributiondata. For example, the following operation is conceivable.

(1) Re-distribution of Distribution Data

The content distribution apparatus 10 transmits distribution data againto the display apparatus 20 as the need arises. On receipt of thedistribution data, the display apparatus 20 generates again a playliston the basis of the received distribution data, although there is theplaylist 2432. At this time, when there is distribution data newer thana replacement rule generated by the replacement rule setting program2444, the content playing program 2442 is configured to play/display thedistribution content, not the replacement content.

(2) Distribution of Replacement List

Although a replacement list is generated on the display apparatus 20side in the above-described embodiments, a replacement list may begenerated on the content distribution apparatus 10 side and may bedistributed to the display apparatus 20.

For example, when the content distribution apparatus 10 sets thefollowing replacement rule:

Frame1→[

Mainserver

Folder1]

the content “Frame1” is forced to be replaced with the details in theshared folder.

In addition, when the following replacement rule is set and isperiodically distributed:

CM1.jpg→CM1.jpg

even if the display apparatus 20 sets the following replacement rule:

CM1.jpg→ETC1.jpg

the replacement rule is forced to be rewritten. Accordingly, for thedisplay apparatus 20, the content “CM1.jpg” becomes content that is notreplaceable.
